ALTON — An Alton man pleaded guilty Thursday and was sentenced to seven years in prison for committing sex offenses involving a 15-year-old, after a previous conviction of abusing a 5-year-old.

Elijah D. Burnett, 23, of the first block of 13th Street, pleaded guilty to two counts of aggravated criminal sexual abuse. In that case, he was accused of sex acts with the 15-year-old victim between Oct. 1 and Nov. 26.

He was sentenced last July to four years of probation after being convicted of molesting a 5-year-old, which was revoked due to the new case.

The most recent case was reported to police by the victim’s mother. Burnett and the victim became acquainted through a friend of a friend, authorities said. Burnett was listed on the Illinois Sex Offender Registry as a sexual predator at the time.
